The 0.5W 3xAAA Flashlight (hereinafter just called a "flashlight") is a small handheld flashlight that you can stuff in your pocket (if you have larger pockets) or a purse to provide light whenever you need it.

It features a 0.5 watt high-output LED, and feeds from three AAA cells. These are held in a carriage in an almost all-aluminum housing; this was shown to be waterproof - not just water-resistant.


SIZE



To use this flashlight, feed it first (see below), and then you can go to town.

Press the rubberised tailcap firmly until it clicks and then release it to get light. Press and release it the same way again to not get light.

This flashlight does not have a LOTC (Lock Out TailCap). Do not look for or expect to find such a feature.



To change the batteries in this flashlight, unscrew and remove the tailcap, throw it in the {vulgar term for toilet}, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the open end of the barrel in your hand, so that the clear plastic battery carriage slides out of the barrel and into your palm. If necessary, remove and dispose of or recycle the three AAA cells in this carriage. Insert three new AAA cells into the chambers in the carriage, orienting each AAA cell so its flat side (-) negative faces the spring for it in each chamber.

Orient the carriage so the spring faces the open end of the barrel, and insert the carriage into the barrel. Screw the tailcap back on, and be done with it.

Aren't you glad you didn't flush that tailcap away now?

Current usage measures 91mA on the AAA cells that were supplied with it.




Looking "down the barrel", where you can see the LED and reflector.

The flashlight is at very minimum reasonably durable. It withstood my smack test (ten whacks against the corner of a concrete stair; five against the side of the bezel and five against the side of the tailcap), and I found the expected amount of very minor denting on the tailcap and bezel where it was struck. No optical or electrical malfunctions were detected.

The flashlight has a clear Type II anodizing on it. I was able to scratch through the finish with the blade of a Swiss army knife with some difficulty. It is more than reasonably durable though. So it should stay looking new for a long time, even if it goes up against keys, tools, or other flashlights during storage or transportation.
Would I really try to cut up a brand spanken new flashlight?
You bet your sweet patootie I would, if it's in the name of science.

This flashlight is water-resistant. It withstood my suction test, and did not leak at all.

The beam produced by this flashlight is a pure, slightly bluish white. If you showed the beam to a group of people and asked them to tell you what color they saw, I guarantee everybody would holler out "WHITE!!!".

The LED in this flashlight isn't a Luxeon, but it isn't a standard 5mm either. Upon closer examination, there are six bond wires leading into the die (light-emitting region), indicating it may be one of those 100mA high-powered LEDs that can be found at PowerLEDs (formerly ISP Korea).

The lens is plastic. Polycarbonate to be specific, but still plastic. I tried to cut through it with a knife, and was successful.
O, the things I do to poor innocent defenseless helpless little flashlights in the name of science.
